Midas frameworks allow for easy extension by users.
Users can add commands and libraries.
Option trees are the mechanism by which users can add functionality without creating
conflicts with other users who have added functionality.
An option tree is a directory that contains a set of semi-standard subdirectories
that is recognized by the Midas framework.
Path
This is the list of option trees currently in use by the Midas framework.
The path is configurable at runtime.
Java Experts Take Note:
The Option Tree concept is similar to the package concept in Java. In NeXtMidas, the
package names match the option tree structure, with each user's packages beginning
"nxm.<opt>.".
